ens_normalize 1.0.2

Ethereum Name Service (ENS) Name Normalizer adapted from namehash labs and adraffy.

ENS Normalize Dart

• Dart implementation of ENSIP-15 - the ENS Name Normalization Standard.
  • This library is being maintained by the team at Variance.
• Passes 100% of the official validation tests.
• Javascript reference implementation.
• Adapted from JavaScript implementation version 1.9.0 and Python implementation version 3.0.7.

Getting started

dart pub add ens_normalize

Usage

import 'package:ens_normalize/ens_normalize.dart';


void main() async {
  ENSNormalize ensn = await ENSNormalize.getInstance(); // parses normalization in separate Isolate
  // OR
  ENSNormalize ensn = ENSNormalize(); // Passes normalization synchronously

  ensn.normalize('Nick.ETH');
  // nick.eth

  ensn.isNormalizable('Nick.ETH');
  // true

  ensn.cure('Ni‍ck?.ETH');
  // nick.eth

  ensn.beautify('1⃣2⃣.eth');
// 1️⃣2️⃣.eth

  ensn.tokenize('Nàme‍🧙‍♂.eth');
// [
// Instance of 'TokenMapped',
// Instance of 'TokenNFC',
// Instance of 'TokenValid',
// Instance of 'TokenDisallowed',
// Instance of 'TokenEmoji',
// Instance of 'TokenStop',
// Instance of 'TokenValid']

  ensn.normalizations('Nàme🧙‍♂️.eth');
  // [
  // NormalizableSequence(code="NormalizableSequenceType", index=0, sequence="N", suggested="n"),
  // NormalizableSequence(code="NormalizableSequenceType", index=1, sequence="🧙‍♂️", suggested="🧙‍♂")
  // ]

  ensn.ensProcess(

    doBeautify: true,
    doTokenize: true,
    doNormalizations: true,
